Birkhill Fireclay Mine

P. & M. Hurll Ltd., a fire-brick manufacturer based at Glenboig (North Lanarkshire) acquired the Birkhill estate in 1916 and drove a series of adits on both sides of the River Avon in the 1930s. Peak production was in the 1950s and the pillar and stall workings eventually extended for around 6 miles underground in the 1970s just before the company went into liquidation in 1980.

This bridge carried the rails from the adit of Mine No.3 on the west bank to the incline on the east bank that lead up to the processing works. In 1987 the workings were opened as a tourist attraction, but this has been closed for some time now with little sign of an imminent reopening. Sadly the processing works was demolished a short while ago.
